Solution Overview
Problem
Hoses used in various applications can leak, tear, or burst over time, leading to radial expansion before failure, which existing detection methods fail to accurately and timely identify, potentially resulting in damage or accidents.
Innovation Solution
A hose failure detection system featuring a sensor assembly with pivotally coupled arms that form a closed electrical circuit around the hose, which opens to detect radial expansion and includes a leak detection assembly with conductive elements and a fluid-absorbing member to indicate hose failure or leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing detection methods are used, then the system is simple, but the detection accuracy and timeliness of hose failure are insufficient
Solution Approach 1:
The sensor assembly is divided into multiple functional segments: a clamp body with pivotally coupled arms for mechanical detection, electrical contacts for circuit-based detection, and a leak detection assembly with conductive elements and fluid-absorbing member. Each segment performs a specific detection function, collectively achieving comprehensive hose failure detection with high accuracy while maintaining modular simplicity.
2Reliability
If a sensor assembly with pivotally coupled arms is used, then radial expansion detection is improved, but the device complexity increases
Solution Approach 1:
The pivotally coupled arms utilize the hose's own radial expansion as the detection mechanism. When the hose expands radially, it directly acts on the arms to pivot them open, breaking the electrical circuit. The system detects failure through the hose's natural physical change without requiring external power sources or complex actuation mechanisms, achieving high reliability with minimal added complexity.
3Adaptability or versatility
If a leak detection assembly with conductive elements and fluid-absorbing member is added, then leak detection capability is improved, but the device complexity and cost increase
Solution Approach 1:
The leak detection assembly merges multiple detection functions into a single integrated unit. The fluid-absorbing member absorbs leaked fluid and transfers it to conductive elements, which then complete an electrical circuit to signal leakage. This combination of absorption and conduction mechanisms in one assembly provides versatile leak detection capability while avoiding the need for separate sensors and processing systems.

AI summary
A system configured to detect failure of a hose includes a sensor assembly having a body with a first arm and a second arm pivotally coupled to one another at respective first ends, and the body is configured to move between a closed position and an open position. The sensor assembly also includes a first electrical contact positioned at a respective second end of the first arm and a second electrical contact position at a respective second end of the second arm. The first electrical contact and the second electrical contact are configured to contact one another to form a complete electrical circuit when the body is in the closed position and are configured to be separated from one another to form an open electrical circuit when the body is in the open position to facilitate detection of the failure of the hose.
